POWER DISSIPATION ADSP-21060 (5 V)
These specifications apply to the internal power portion of V
DD
only. See the Power Dissipation section of this data sheet for calcula-
tion of external supply current and total supply current. For a complete discussion of the code used to measure power dissipation, see
the technical note “SHARC Power Dissipation Measurements.”
Specifications are based on the following operating scenarios:
Operation
Peak Activity (I
DDINPEAK
)
Multifunction
High Activity (I
DDINHIGH
)
Multifunction
Low Activity (I
DDINLOW
)
Single Function

To estimate power consumption for a specific application, use the following equation where % is the amount of time your program
spends in that state:

NOTES
S
1
The test program used to measure I
represents worst case processor operation and is not sustainable under normal application conditions. Actual internal
power measurements made using typical applications are less than specified.
2
I
is a composite average based on a range of high activity code. I
DDINLOW
is a composite average based on a range of low activity code.
3
Idle denotes ADSP-21060L state during execution of IDLE instruction.
